Title: NNIS


1
  • NNIS
  • NaSH
  • DSN

NHSN
2
General
  • Patient Safety Component is a hybrid of NNIS and
    DSN
  • Healthcare Personnel Component is a hybrid of
    NaSH
  • Focus on Patient Safety Component today
  • Surveillance Plan is still required

3
General Differences
  • Event-specific forms and data entry screens
  • For some events, will indicate which criterion
    was used to identify event (e.g., BSI)
  • Discharge date is required for each event
    reported except DI
  • Patient data can be entered separately from event
    and once entered can be duplicated for
    subsequently entered events

4
General Differences
  • Custom fields on event forms
  • Still optional customizable for each event type
  • More and varied types (2 date, 2 numeric, 10
    alpha-numeric)
  • Can be labelled can be analyzed
  • Text box for comments (cannot be analyzed)
  • Linked to patient record

5
General Differences
  • Custom events
  • Optional all fields shown are optional
  • Contain custom fields and custom text box
  • Used for
  • Collecting additional events that are not
    collected under a module but have a NHSN
    definition (e.g., gastroenteritis due to C.
    difficile)
  • Collecting events that deviate from NHSN
    definitions (e.g., MYBSI)

6
General Differences
  • Requirements for enrollment
  • Must be from a bona fide healthcare facility or
    delivery venue (CMS or AHA number, VA station
    code)
  • Must have email address and internet access on
    computer used for reporting
  • Must be able to download a digital certificate
    onto that computer

7
General Differences
  • Requirements for enrollment (cont.)
  • Must complete enrollment survey
  • Personnel listing
  • If hospital, survey similar to annual survey in
    NNIS
  • Must complete and return consent form by surface
    mail
  • Agree to follow protocols and use definitions
    exactly
  • Send acceptable data 6 month every year,
    including annual survey

8
NHSN Timeline
  • Now until mid-2004 Design, develop, and
    internally test application develop training
    materials
  • Mid- 2004 Pilot test application revise
    conduct training sessions begin enrolling
    current members
  • Fall/Winter 2004 Make available to current users

9
Training
  • Elements include
  • Video conferences that can be viewed live and
    later
  • Enrollment and requirements for participation
  • Protocols
  • How to do data entry
  • How to do data analysis
  • Online tutorials
  • Online help messages and manual
  • Printable forms and manual

10
NNIS Legacy Data
  • Cannot import your NNIS data into NHSN
  • Data on your hard drive do not match those in the
    NNIS database (e.g., no patient names at CDC)
  • Database structures are different in NNIS and
    NHSN
  • Will send you a program that converts NNIS data
    to a format suitable for import into popular
    spreadsheets/databases
  • Will provide a method that allows import of NNIS
    rate data into NHSN spreadsheet reports

NNIS ICU Component to NHSNDevice-associated
Module
  • What do we lose?
  • Incidence and distribution of infections at all
    sites in ICU/HRN
  • Pathogen distribution for infections other than
    CLABSI, VAP, CAUTI
  • What do we gain?
  • Flexibility for selecting the event and
    population under surveillance
  • Information on which diagnostic criteria were
    used
  • Information on DA infections in nonICU locations

NNIS SP Component to NHSNProcedure-associated
Module
  • What do we lose?
  • Comparison with some legacy data due to coding
    changes (e.g., FUSN split into FUSN and RFUSN TP
    and VS split into new specific categories )
  • What do we gain?
  • More flexible and efficient data collection on
    more surgical patients and on more discrete
    procedures
  • Improved risk-adjustment techniques (can use risk
    models and risk index)

33
NNIS SP Component to NHSNProcedure-associated
Module
  • What do we gain?
  • Ability to link BSI, PNEU, and UTI occurring
    after an operative procedure to the procedure
  • Calculate rates by type of procedure
  • Ability to monitor procedure-associated pneumonia
    regardless of whether a ventilator is used by
    type of operative procedure
